Yaskawa Electric Corporation announced the Yaskawa website restoration on October 26, 2026, at 14:50 Japan Standard Time. The company had suspended its sites because of a PHP vulnerability. It said it applied the necessary countermeasures, confirmed the sites were safe, and brought them back online.
Yaskawa also said it found no unauthorized access, no data leakage and no other damage caused by exploitation of the vulnerability. That statement is the central claim of the announcement, and it covers only what the company says it found.
Which sites are back
Yaskawa named three sites as restored. The first is the YASKAWA Official Site for Japan, at www.yaskawa.co.jp. The second is the YASKAWA Global Site, at www.yaskawa-global.com. The third is the e-Mechatronics Website, at www.e-mechatronics.com.
The company said other partner-related websites have also resumed operation. Some of their functions are temporarily limited. It did not say which partner sites are affected, which functions are restricted, or when full service would return.
The Global Site is the main English-language route into Yaskawa's product, investor and corporate information. Its navigation covers servo motors, AC drives, industrial robots, system engineering, and energy saving and creation. It also covers customer case studies, investor relations, sustainability reporting and regional contacts across the Americas, Europe, Asia Pacific, and the Middle East and Africa. The restored page itself carries that full structure again, including the region selector for local sales companies.
What Yaskawa did and did not say
Yaskawa's statement is short. It says the sites had been suspended due to a PHP vulnerability. It says countermeasures were applied. It says safety was confirmed before the sites returned. It then states that no unauthorized access, data leakage or other damage was found.
Several details are absent. The company did not give the date the suspension began, so the length of the outage cannot be stated. It did not identify the specific vulnerability or any CVE identifier. It did not describe the countermeasures, whether they were a software update, a configuration change or something else. It did not say how the vulnerability was discovered, or whether an outside party reviewed the sites before they were reopened.
Yaskawa closed with an apology for the inconvenience during the suspension and thanked visitors for their patience. It added that it will continue its efforts to provide safe and reliable websites.
Why a robot maker's web outage is worth noting
This is not a robot failure. No Yaskawa robot, controller or servo product is mentioned in the statement, and nothing in it suggests that products in the field were affected. The incident concerns the public web presence of a company whose business is industrial machinery.
The web presence still matters to customers. Yaskawa's site hosts its technical material, including core technology pages, a technical review, a technical history and sections on servo motors, AC drives, controllers and robotics. It also hosts a product security initiatives section. Integrators and maintenance teams who depend on documentation and contact routes lose access to them when the sites go dark. The inclusion of the e-Mechatronics site in the restoration list shows the suspension reached beyond the corporate front page.
Analysis: what the restoration does and does not establish
The decision to suspend the sites rather than leave them running suggests the company judged the vulnerability serious enough to justify an outage. That is an inference from the action, not something Yaskawa stated. Taking sites offline is a costly step for a global manufacturer, because it cuts off customers, investors and partners across many regions at once.
The claim that no unauthorized access or data leakage occurred is the part readers cannot test. Yaskawa gave no account of how it reached that conclusion. It did not describe logging, forensic review or third-party verification. A statement of absence is only as strong as the evidence behind it, and that evidence has not been published. Readers should treat it as the company's finding, not an independently confirmed result.
The limited functions on partner sites are a second open point. Restoration appears to have been staged, with the three main sites returning first and partner sites following with reduced features. That ordering is reasonable, but it means the incident was not fully closed on the day of the announcement.
Compared with the robotics field more broadly, the episode is a reminder that manufacturers' web infrastructure sits in the same security picture as their products. Yaskawa already maintains a product security initiatives section on its site. This incident involved the web layer, not the products, and the company has not linked the two. Any claim that product security was touched would go beyond what is stated.
What remains unproven is the durability of the fix. The company says the countermeasures were applied and safety confirmed, but it has not said what was changed or whether the same class of flaw could appear elsewhere in its estate. A fuller account would name the vulnerability, give the outage window, and describe how the no-damage finding was reached. Until then, the restoration shows the sites are back and the company reports no harm. It does not show how the problem arose or how thoroughly it was ruled out.
